Postcode Sectors Grid References - Scotland

Postcode sector grid references are created and maintained by National Records of Scotland (NRS). Grid references are calculated based on the Royal Mail Delivery Point Count of the postcodes within the postcode sector, while ensuring that the centroid is located inside the boundary.

NRS publish these grid references twice a year as part of the Scottish Postcode Directory (SPD) which should be considered the definitive source for postcode geographies in Scotland.
